Description and Introduction

Octal D-Type Transparent Latches With 3-State Outputs The SN74ALS563BN is a 8-bit transparent D-type latch with 3-state outputs, manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** D-Type Latch  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Output Current (IOH):** -2.6 mA  
- **Low-Level Output Current (IOL):** 24 mA  
- **Propagation Delay Time (tpd):** 12 ns (max)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-20  

### **Descriptions:**  
- The SN74ALS563BN features an 8-bit transparent latch with 3-state outputs.  
- It is designed for bus-oriented applications.  
- The outputs are disabled when the output enable (OE) input is high.  

### **Features:**  
- **3-State Outputs:** Allows connection to a bus system.  
- **Buffered Control Inputs:** Reduces loading effects.  
- **High-Speed Operation:** Optimized for performance in ALS logic family.  
- **Wide Operating Voltage Range:** Compatible with 5V systems.  
- **Latch Enable (LE) Input:** Controls data transparency.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and timing diagrams, refer to the official documentation.

Application Scenarios & Design Considerations

Octal D-Type Transparent Latches With 3-State Outputs

Alternative Part Number

  • 74ALS563BN --: Same 74ALS octal D-type transparent latch with 3-state outputs, pin-compatible and functionally equivalent.
  • DM74ALS563BN --: Direct equivalent ALS-series octal latch in the same DIP-20 package with matching logic function.
  • SN74ALS563B --: Same TI ALS octal latch family in alternate package option, electrically equivalent to the original.
  • 74ALS563AN --: Equivalent 74ALS563 octal latch in DIP package with matching logic function and pinout.
  • SN74HC563N --: Same octal transparent latch function and pinout; HC family offers lower power but slower speed, acceptable in many non-critical designs.
